If you really want to understand my goal you can try to read my the next
article (sorry for bad english):
http://unde.sf.net/estimation-resources
If shortly I just want to estimate CPU using by program also as other
resources like memory.
I just try test `time` output (it prints user time and sys time for any
program in Linux) for loaded and not loaded system and looks like that for
Linux getrusage is what I need.
As I understand there is no any universal methods to get this information
for any OS?

If you're looking to time how long a function takes to call, then use

program calls a particular function and how much time it spends in that
function, then compile with -profile, run the program, and then look at
the
files that it generates. If you want to do the equivalent of -profile at
runtime, I don't think that that's really possible, and I'm not quite
sure why
you'd want to. But even if you could, it would affect the performance of
the
program and probably skew the results anyway. It would certainly slow
down the
program a lot. I suppose that you could write a wrapper function for your
specific function, time the exact time that it takes on each call with
std.datetime.StopWatch, and then send that information to another
process via
std.socket if you really want something like that. But that sort of thing
sounds rather complicated to me, and I have no idea what good the
information
would do you at runtime anyway. Usually, the reason that people want to
profile
code is to determine what code they need to optimize make the program
faster,
and -profile is plenty for that.
